Letters Patent No. 95,582

, dated October 5, 1869.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom 'it may concern:

Be it known that I, WILLnM P. HALE, of Ionia, in the county of Ionia,and State of Michigan, have invented certain new and useful Improvementsin Lathreference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecilication, and in which Figure l represents aside elevation of mymachine. Figure 2 is a central cross-section. Figure 3 is a plan view.The nature of my invention consists in the employ-V ment of two or morecollars on the main or drivingshaft, by means of which the saws are heldin posioperated ata time.

It further consists in the peculiar construction of the platform forholding the lath-timber, in combination with other devices, thepeculiarity of which will be hereafter described.

ln thenccompanying drawings- A represents the frame of my machine,constructed in a rectangular shape.

B represents the main shaft, provided with drivingrlhe shaft B issecured in journals b b, attached to the upper surface of flame A.

On the projecting end of shaft B, and near the driving-pulley a, issecured the grooved-pulley f, the obiect of which will be hereafterdescribed.

On theopposite end of shaft B the saws c c c are adjusted, and separatedby means of hollow collars d al d, formed with slightly spiral arms,with an open space between them, s o as \to admit a free circulationsaws from heating.

The saws are held firmly in place by means of a nut, c, which pressesagainst the outside collar d.

By this arrangement any number of saws may be attached to the projectingend of the shaft B.

D D D D represent four metal uprights, secured to the side of frame A byscrew-bolts. (See fig. 1.)

In these uprights are placed the shaftsN N N N, two being assigned toeach pair of uprights, and working in journals, one above the other.

The followers, which confine the upper shafts in uprights D D', areprovided with a spiral spring, n, to keep the said followers in place,and give them the required pressure on the shaft.

F F represent rollers, 011 the ends of the shafts N N, opposite to thesaws c c o.

The rollers marked G G, it will be observed, are provided withcorresponding flanges, g g y, lwhich are designed as guides to the lathsafter they have passe from the saw. M M represent spur-wheels, securedto the shafts N N, for the purpose of giving motion to the rollers G G.

P represents a platform, resting at one end of the 1) p represent metalsprings, the innerends of which are secured to the frame A, andbent'upward at right angles at their outer end, audthen made to passthrough holes in the platform P.

, The ends projecting over the platform P are ntended to act as guidesto the lat-h-timber.

When it is desired to have the three saws cutting at the same time, thetimber will press the guidesI down', and move on the smooth surface ofthe platform, being carried forward by the rollers F 14.

c e represent two grooved wheels, one being secured to the projectingendof each of the lower shafts N N.

The said wheels are put in motion by a band passing around the groovedpulley f,.and the'moton communicated'to the upper shafts by thespur-wheels M M.

Havingr thus described my invention, What I claim, and desire to secureby ent, is-
